Summary

ALL ABSORPTION HEAT PUMPS COMPRISE A SEPARATOR IN WHICH THE CONSTITUENTS OF A BINARY MIXTURE ARE SEPARATED BY DISTILLATION AND A MIXER IN WHICH THESE CONSTITUENTS ARE REMIXED BY REVERSE DISTILLATION. THE SEPARATOR IS THE SITE FOR THERMAL EXERGY CONVERSION INTO CHEMICAL EXERGY AND THE MIXER IS THE SITE FOR REVERSE CONVERSION. A MULTISTAGE HEAT PUMP IS MADE UP OF AN N-STAGE SEPARATOR AND AN M-STAGE MIXER. SUCH A TRANSFORMER IS AN EXERGETIC QUADRUPOLE PRESENTING LARGE ANALOGIES WITH AN ELECTRICAL TRANSFORMER, THE PRIMARY WINDING OF WHICH WOULD BE MADE UP OF N-COILS AND THE SECONDARY WINDING OF M-COILS. THE AUTHORS PROPOSE A SIMPLE PROCESS FOR MANUFACTURING MULTISTAGE HEAT PUMPS CONSISTING OF COUPLING RECTANGULAR CELLS. LIQUID FILMS FLOW FACE TO FACE ON THE WALLS WITH ONE EVAPORATING AND THE OTHER CONDENSING OR ABSORBING VAPOUR.
